    I have found that it is extremely satisfying to homebrew a radio and take it out to the field and see it working. I never got that feeling from a store bought radio. I sit listening to Shortwave in the living room and glance over at my homebrew radio and smile with satisfaction.

    Extremely awesome small QRPp transceiver. Received audio was extremely clean and pleasant. Congratulations and thanks for sharing this awesome home brew project.....James VA7VB

    Nice work and use of your 3-D printer to make the various parts; you gave me some ideas for sure.
    Also, I was very surprised at the sound of the receiver.
    You did a great job and thanks for putting it into a video for all to see.

    Absolutely excellent job, such a nice sounding receiver with so few parts! And your tiny ATMega328 and si5351 board is brilliant too. No tuning, no display, half a watt and the builtin antenna tuner is well thought through. I love it! Will look at your other projects next.

      Thank you for writing about my design.
      I had planned for the frequency to come out with Morse code in the earphone, but the software has not been written yet.

    When I was a teenager, I used to love to build little projects, but never built anything beyond a crystal receiver. Your example inspires me to want to build a QRP transceiver sometime soon. KK7PQJ

    Wonderful. I wonder what radio (s)was carried by the Norwegian Commandos who raided the heavy water plant ( Vemork) at Telemark during World War II?. I grew up watching the movie " The Heros of Telemark" as a boy in Oregon.

      @@LA6NCA Hello Mr Helge. I have an idea on how to further simplify the circuit. We can get rid of the signal relay to the mixer. SI5351 has 2 VFOs inside. The output of VFO 1 can be directly fed to the mixer, and the output of VFO 2 can be fed to the amplifier transistors. Based on the TX signal, VFO 2 is turned on and the F-600Hz signal is supplied to the amplifier. In RX mode, VFO 2 is disabled.
      Your transceiver is beautiful in its simplicity! Can I place your design on various radio engineering sites and my telegraph group, with a link to your site?
